In this July 11, 2007 file photo, the home of President-elect Barack Obama is shown in Chicago. Places that U.S. presidents have called home often become major tourist attractions, from estates at Mount Vernon and Monticello, to Hodgenville, Ky., where Abe Lincoln's log cabin once stood. But if you want to see all the places connected to Obama's life story, you'd need to visit three countries, five time zones and six states.
